lne principal objects of the invention are to minimize the dangerof flooding in oil hurningfurnaces in the event of the failure of the ignition, and to provide avery compact arrangement for the purpose which will receive any oil escaping unburned from the nozzle and from which said oil niay'be Very easily discharged prior to re-starting the burner into operation.

The principal features of the invention consist in the novel construction of a receptacle casino which is pivot'ally mounted on theend of the overflow pipe leading from the combustion chamber to receive the discharge therefrom, the casing being adapted to he swung on its pivotal mounting to drain the oil therefrom and being adapted to house a suitable switch mechanism actuated by a float in the casing.

A further feature consists in providing a stop on the casing adapted to engage the overflow pipe to limit the swinging movement of the casing thereon.

In the drawings, Figure 1 is a perspective view of the casing showing its arrangement on the overflow pipe in lts overflow recelving position.

Figure 2 is a perspective view of the device illustrated in Figure 1 showing the manner in which the receptacle may he swung to'eifect the removal of the-oil therefror Figure 3 is a part section, part elevational View of the device illustrated in Figures 1 and 2. i in the type of power driven oil burners now so extensively used for domestic heating purposes it is particuiariy desirable that'some means he provided for taking care of the discharged oil in the event of the failure of the oil toignite, due oftento an interruption in the ignition. v

it has been found that under such conditions and with present equipment in the event of failure of the flame at the burner for some reason other than the actual shutting oii of the power, the oil will still continue to be delivered to the burner by the pump and this oil failing to ignite flows down into the furnace and rapidly floods the same.

In our co-pending United States applica t 2 5 a N9 403% fi d J n 29, 925, We h ve d s ri ed a 'a u ma ie f rm f t'o l which is actuated this excess amount of oil in the furnace to effect the shutting off ofthe main motor circuit in the event of the furnace becoming flooded, so that the motor will diecontinue pumping further ,oil to the burner. h Pr s t application is a d v qn it i plication- Ser. No. 40,34z0 such application being W Paar me s eed NOV: 9,

The Pres nt inv nti s di ed be a ar ticularly effective means foftaking care of the excess or overfiow'oil furnace from which the oil may be very conveniently a d kl em t d $9 the i e fe lly re-set before the burner is again setv into operation, it be ng-i portant thatsuch apparatus cannot be left i an inoperable condition." i A ii i In the construction herein shown the overflow pipe 1' whichleads from the furnalce 'is connected to a suitahle pan or other," receiver that will readily'catch' the liquid oil discharged from the burner nozzle when his not being ignited.

The pi e 1 leads outside of the furnace and extends into a casing 2 which is p vepaliy mounted" upon the .pin" 3' which extends through the pipe close to its outer end and through thelugs 4i iirthe side of the casing.

i The said casing is formed with a substantially cylindrical well portion '5 'which is adapted to house the switch actuating float 6 as fully described in our co-pending'applicav' tion abovereferred to.

"ihe side portions 7 of the lugs 4; extend forwardly inthe form of a lip whlich fits snugly around the underside of the pipe 1 and connects with sloping spout-shaped poitiori8 which preferably extends well down to the lower extremity of the cylindrical float well portion 5 forv a purpose tohe re,-

ferred to A cover 9 closes the top of the well 5 and is P v d wit an p a y ilg l i :0 the forward side. which registers with the de allslei h new and aim t e ing to b swung o'rflop d upwardly 9th? p s tion h w in ree. .7 2 Wh je" th iP engages the top of the pipe 1 and arrests the casing against further movement.

A suitable casing 11 is mounted on the cover 9 which forms a convenient housing for a suitable switch mechanism to which the float is adapted to be connected.

In the event of the liquid oil escaping from the burner and flowing through the pipe 1, it flows into the'well 5 where it is adapted to raise the float 6 therein as described in our co-pending application for the purpose of operating the electric switch to stop the operation of the burner mechanism. 7

Before starting the burner into operation again, it is necessary to drain the oil from the float well '5 and this is accomplished in a very simple manner by merely tilting the casing 2 upon its pivotto the position shown in Figure 2 "which allows the oil to flow therefrom out of the spout 8, which as previously stated extends well down to the lower extremity of the float well portion 5 so that the oil will be completely drained therefrom.

The lip 10 effectively prevents the casing from being tipped past the centre of gravity so that when it is released, it will swing back of its own weight to its normal position on the pipe 1 and remain in this position in readiness should a further overflow of oil occur. I

In this way the casing cannot be accidental- 1y left in a position where it will not receive the overflow, and when used in COI1]U.I1CtiOl1 with the float actuated switch mechanism described in our co-pending application will provide a very compact and desirable combination which will ensure definite protection from the dangers attending the flooding of oil burning furnaces. 7

What we claim as our invention is:

1. An overflow receptacle for oil'burners, comprising the combination with an overflow pipe, of a casing pivotally secured at the end of said overflow pipe and having a float well formed therein adapted to receive a float, said casing being formed with a spout extending angularly upward from the lower extremity of the float well and embracing said pipe at the upper end, said spout being adapted when the casing is tilted upwardly on its pivot to drain the oil from said float well, and a cover secured to said casing having a lip sloping upwardly above said overflow' pipe and adapted to engage the latter to limit the upward tilting movement of the casing.

2. An overflow receptacle for oil burners, comprising'the combination with an overflow pipe, of a casing pivotally suspended from said pipe and adapted to receive the discharge therefrom, said casing being adapted to be tilted on said pivot andha-ving a drain channel sloping angularly outthe complete draining of the oil therefrom will be effected with the minimum pivotal movement of said casing.

3. An overflow receptacle for oil burners, comprising the combination with an overflow pipe, of a casing pivota-lly suspended from said pipe and adapted to receive the discharge therefrom, and a spout in said casing receiving the outer end of said overflow pipe, said spout being sloped angularly outward from the bottom of the casing whereby upon the tilting of saidcasing on its pivot a limited degree the oil will be completely drained from said casing.

l. An overflow receptacle for oil burners, comprising the combination with an overflow pipe, of a casing having a pouring spout sloping outwardly and upwardly from the normally lowermost portion thereof and receiving the discharge end of saidpipe, said, spout havmg side lugs arranged at oppos1te sides of the pipe, a pin spaced from the outer extremity of said spout and extending through said pipe and lugs and pivotally securing the casing to the pipe, the outer portion of said spout engaging said pipe to normally support the casing in an upright position, said spout being adapted on the tilting of said casing on'its pivot a limited degree to direct the' oil completely therefrom through said spout. i

5. An overflow receptacle for oil burners, comprising the combination'with an overflow pipe, of a casing pivotally suspended below and receiving the discharge from said overflow pipe, said casing having a float well thereinextendedlaterally to one side forming a pouring spout sloping outwardly and upwardly from the bottom of the float well and adapted on the limited upward swinging of the casing on its pivot to drain the oil completely from said well, and means for limiting the upward swinging movement of said casing.
